On the Burst Erasure Capability of Spatially Coupled LDPC Ensembles

  • Aref V.
  • Rengaswamy N.
  • Schmalen L.

Spatially-Coupled LDPC (SC-LDPC) ensembles achieve the capacity of binary memoryless channels, asymptotically, under belief-propagation decoding. In this work, we are interested in the finite-length performance of these ensembles on binary channels with memory. We study the average performance of random regular SC-LDPC ensembles on the single block erasure channel and ...

The Future of Communications

  • Hofmann M.
  • Lee A.
  • Olofsson B.

The essence of communication is the imparting or exchanging of information. We can broadly define three primary types of communication personal, media, and control type communication, each of which results in the exchange of information between people or systems. Personal communication can be regarded as the exchange of information or ...

Advertising Competitions in Social Networks

  • Masucci A.
  • Silva Allende A.

In the present work we study the advertising competition of several marketing campaigns who need to decide how many resources to allocate to potential customers to advertise their products through direct marketing while taking into account that competing marketing campaigns are trying to do the same. Potential customers express a ...

Next-Generation Forward Error Correction: Can we Close the Gap to the Shannon Limit?

  • Aref V.
  • Roesener D.
  • Schmalen L.
  • Suikat D.

We report the current status of forward error correction schemes and show how close we can operate to some theoretical limits taking into account the size of the codes. We show that spatially coupled LDPC codes are good candidates for bridging the gap to capacity and compare some practical codes ...

IoT - Impact on Mobile Networks

  • Dhingra V.

IoT is poised to revolutionize industries and ways we live and work. These things will digitally connect to other devices and the network via multiple technologies. MNOs are making significant investments in M2M communications for providing connectivity as well as value added services to IoT application providers and enterprises. However, ...

The Future of Information

  • White C.

We sit on the cusp of a revolution in information driven by the intersection of a massive increase in the sources of data and the ability to augment our intelligence and use critical thinking to turn this data into knowledge. Information can be defined as the communication or reception of ...

Globally Convergent Algorithms for Blind Source Separation

  • Papadias C.

We present a nobel class of adaptive algorithms for the blind separataion of non-Gaussian mutually independent source signals that can be modeled as independent identically distributed (i.i.d) discrete random processes. The signals are assumed to be transmitted through a m x p narrow-band (instantaneous linear mixture) channel. The original algorithm, ...

SIP message prioritization and its applications

  • Batteram H.
  • Meeuwissen E.
  • Van Bemmel J.

Session Initiation Protocol (SIP) signaling is an integral part of the IP Multimedia Subsystem (IMS) to support services such as Voice over IP (VoIP), multimedia sessions, presence, and instant messaging (IM). All of these services share a common SIP signaling infrastructure. In spite of careful network engineering, SIP network elements ...

XStream: a Functional Language for Distributed Stream Processing in the Edge Cloud

  • Cortes M.
  • Dobbelaere P.
  • Hoste L.
  • Philips E.
  • Roelands M.
  • Sheykh Esmaili K.
  • Trappeniers L.
  • Van Cutsem T.
  • Van Raemdonck W.
  • Verdot V.

Internet of Things (IoT) data and video traffic is forecasted to explode within the coming decade. Characteristic of such streams is that they are highly context-dependent and rarely consumed by humans. Traditional "big data" architectures are a bad fit for intelligently processing this large variety of streams as they usually ...

Social fingerprinting: detection of spambot groups through DNA-inspired behavioral modeling

  • Cresci S.

A Novel PCS Lane Management Mechanism For High-Speed Ethernet

  • Chen Y.
  • Liu D.

In high-speed Ethernet such as 40G/100G Base-R, multiple PCS lanes are used usually to transport data. When any lane cannot be synchronized or aligned, traffic will be broken and this greatly wastes datawidth. A Novel PCS Lane Management Mechanism For High-Speed Ethernet is presented here. This mechanism can ensure data ...
